I saw that all the I9505 (S4) 4.4.2 firmware have the same changelist
Newer NB6 has the same changelist as NA7 , not understand anything
No, it's not the error. You're forgetting about the fact that the operator needs time (usually a month or so) to release it's branded version, and therefore after a month or so we can get a ROM with one-month-old sources.
Changelist is being generated automatically during building the ROM, you can trust whatever you want, if ROM built yesterday from half-year-old sources satisfy you only because it was built yesterday, feel free to use it. I trust the changelist.
